Trolley Jack is ruining my underseal

[daddycool]

finally realised that black sticky stuff on my trolley jack is the cars underseal. i'm jacking on the chassis legs but the jack isn't moving much with the car and is taking the underseal off.

is normal hammerite sufficient or would you do it properly with likes of

hammerite underbody seal or tetroseal

Foam between the car and jack?

 

[daddycool]

new jack > foam
but i'll use foam too.
it never use to wreck the underseal, only when the jack became a little hesitant to move.

Standard hammerite is more than ok mate

Also waxoyl underseal is pretty similar to whats on there
